Charles and Johnson will join the family of Knoxville resident Pierce Corcoran at the address. The Corcorans were invited by Rep. Tim Burchett and Sen. Marsha Blackburn after their son, Pierce, was killed in a wreck with a suspected undocumented immigrant.

Matthew Charles was required to return to prison after release

Advocates and experts have argued that Charles' original sentence was unfair because punishments at the time were much lower for people convicted of dealing powder cocaine — Charles' conviction was related to crack cocaine.

In 2015, former federal judge Kevin Sharp agreed Charles deserved a shortened sentence. As a result, Charles was released in 2016. He did not re-offend.

But after an appeals court reversed Sharp's ruling, Charles was ordered to serve a full 35 years behind bars. As Charles prepared to return to prison in 2018, his case received national attention in part due to coverage from Nashville Public Radio.

Federal public defenders representing Charles asked for his sentence to be lowered on Dec. 27, days after the new sentencing reform First Step Act was signed by President Donald Trump.

He was released in early January.

"While in prison, Matthew found God, completed more than 30 bible studies, became a law clerk, taught GED classes, and mentored fellow inmates," a release from the White House stated.

Alice Johnson: after release works in criminal justice reform

Last summer, Trump granted the mother of five children, grandmother of six and great-grandmother, clemency from a life sentence she was serving on drug charges. Johnson was convicted in 1996 for five counts of drug trafficking and one count of money laundering, leading to the life sentence despite it being her first offense.

"During her nearly 22 years of incarceration, Alice accomplished what has been called an 'extraordinary rehabilitation.' After her release, she was overjoyed to be reunited with her family," the White House release stated.

Johnson said she owed a "debt of gratitude" to Trump and other who advocated on her behalf.
